#
# TODO 0: Add your information below for Programmer & Date Created. #
# PROGRAMMER: Yuzana Win
# DATE CREATED: 2023-11-02
# REVISED DATE:
# PURPOSE: Classifies pet images using a pretrained CNN model, compares these
# classifications to the true identity of the pets in the images, and
# summarizes how well the CNN performed on the image classification task.
# Note that the true identity of the pet (or object) in the image is
# indicated by the filename of the image. Therefore, your program must
# first extract the pet image label from the filename before
# classifying the images using the pretrained CNN model. With this
# program we will be comparing the performance of 3 different CNN model
# architectures to determine which provides the 'best' classification.
#
# Use argparse Expected Call with <> indicating expected user input:
# python check_images.py --dir <directory with images> --arch <model>
# --dogfile <file that contains dognames>
# Example call:
# python check_images.py --dir pet_images/ --arch vgg --dogfile dognames.txt

# replacements your function call should look like this:
# adjust_results4_isadog(results, in_arg.dogfile)
# Adjusts the results dictionary to determine if classifier correctly
# classified images as 'a dog' or 'not a dog'. This demonstrates if
# model can correctly classify dog images as dogs (regardless of breed)

# TODO 6: Define print_results function within the file print_results.py
# Once the print_results function has been defined replace 'None'
# in the function call with in_arg.arch Once you have done the
